What is Variance-stabilizing transformation?
- Variance-stabilizing transformation In applied statistics, a variance-stabilizing transformation is a data transformation that is specifically chosen either to simplify considerations in graphical exploratory data analysis or to allow the application of simple regression-based or analysis of variance techniques.
- What else did you find interesting?
- The aim behind the choice of a variance-stabilizing transformation is to find a simple function "ƒ" to apply to values "x" in a data set to create new values such that the variability of the values "y" is not related to their mean value.
- Do you have any examples?
- For example, suppose that the values x are realizations from different Poisson distributions: i.e. the distributions each have different mean values "μ".
- What else did you find interesting?
- Then, because for the Poisson distribution the variance is identical to the mean, the variance varies with the mean.
- Are there any other interesting aspects about this article?
- 
Next turn: However, if the simple variance-stabilizing transformation  is applied, the sampling variance associated with observation will be nearly constant: see Anscombe transform for details and some alternative transformations.

DIALOG:
What is special about St Mary's Church, Derwen?
- The church is listed by Cadw at Grade I because of its "possessing an exceptionally complete rood screen and loft and otherwise retaining much of its mediaeval character".
- Are there any other interesting aspects about this article?
- 
Next turn: The architectural historian Edward Hubbard states "the church indeed enjoys the rare good fortune of having a rood screen which retains its loft".

DIALOG:
What were Alan Moore's early years like?
- At the same time, he began reading comic strips, initially British strips, such as "Topper" and "The Beezer", but eventually also American imports such as "The Flash", "Detective Comics", "Fantastic Four", and "Blackhawk".
- Are there any other interesting aspects about this article?
- He later passed his 11-plus exam, and was therefore eligible to go to Northampton Grammar School, where he first came into contact with people who were middle class and better educated, and he was shocked at how he went from being one of the top pupils at his primary school to one of the lowest in the class at secondary.
- What did he do after that?
- Subsequently, disliking school and having "no interest in academic study", he believed that there was a "covert curriculum" being taught that was designed to indoctrinate children with "punctuality, obedience and the acceptance of monotony".
- What were some of his first works?
- 
Next turn:
In the late 1960s Moore began publishing his own poetry and essays in fanzines, eventually setting up his own fanzine, "Embryo".
